A small team of researchers at the University of Manchester has developed a technique for creating a molecular-based, finite-state machine. Their research was published in the journal Nature. In ...

When British mathematician Alan Turing conceived the notion of a universal programmable computing machine, the word computer typically referred not to an object but to a human being. It was 1936, and ...

A theoretical computer built in a mixed-up mathematical universe might not sound like the most practical invention. But the discovery shows that computation can turn up in the most unlikely places, ...
